goods, wherein a plunger is provided for ejecting the packages, and a coin released lock for preventing the movement of the plunger until released by the insertion of a coin, and a follower for moving the packages beneath the plunger, operated by the movement of the plunger to advance the packages.

In the present embodiment of the invention, a casing 1 is provided, having a magazine 2 in WhICh the packages 3 of goods are arranged, and at the forwardend of the magazine there is an outlet 4 in the bottom of the same,- through which the packages may be pushed by the plunger 5 which is mounted to slide in the casing vertically at this point. In front of the magazine is a coin chamber or receptacle 6, and below the opening 4 is a delivery chute 7 having its bottom inclining downwardly and for- Wardly to the outlet 8 of the chute. The foremost package in the magazine is held directly above the opening 4, and to prevent its accidental disengagement a plate spring 9 is secured to the bottom of the magazine at this point, the spring extending slightly into the ath of movement of the package.

The plilnger 5 has intermediate its ends and at the top of the coin chamber 6, when Specification of Letters Patent.

the plunger is elevated, a transverse slot or opening 10, and within this openin is adapted to engage a locking bar 11, the ar being normally pressed into engagement with the opening of the plunger by a coil spring 12 arranged between the bar and a bracket or keeper 13 which is secured to the top of the coin chamber.

A slide 14 is mounted to mOVGdILEL slot in the front of the casing in the coin receivi chamber 15, which is directly above the com holding chamber 6. This slide is normally pressed toward the plunger by means of a coil spring 16 arrangedbetween the slot and the bracket 13, and it will be noticed that the outer end of the slide is upturned to form afinger piece for convenience in manipulating the same. The casing just above the coin receiving chamber ha a slot 17 through which a coin of the proper denomination may be inserted, and there is a guide chute 18 below the slot for guiding the coin toward the bar 11 and the slide '12.

Referring to Figs. 5 and 6, it will be noticed that the bar 1 1 has a notch 19 in the edge adjacent to the slide 14, and the slide has a imilar notch 20 normally registering with the notch of the bar, and both bar and slide are mounted to move in guides 21 in the casing. These notches 19 and 20" have an aggregate width corresponding to the diameter of the coin to be inserted, and normally they stand directly beneath the chute 18, so that when a coin is dropped through the slot it will fall into the notches 19 and 20. When now the slide is pulled outwardly [by means of the finger-piece it will be evident that because of the engagement of the coin with the notches 19 and 20 the locking bar 11 will be moved with the slide, thus releasing the plunger so that it may be moved downward.

Referring to Figs. 5 and 6, it will be noticed that the outer corner of the notch or recess 20 is beveled, as shown at 22, fora purpose to be presently described, and the dividing wall of the chambers 6 and 15 has an opening 23 through which the coin 24 may drop, when it has served its purpose, into the holding chamber 6.

When the locking bar is pulled outwardly by the slide it would immediately be returned to locking position when the slide is released, were not some'means provided for holding it in outward position. The said means is a awl or latch 25 which is pivoted to a pair of lugs 26 on a species of carriage 27 which is mounted to slide in a casing 28 held by the bracket 13 before mentioned. This carriage has outwardly extending pins 29 which move in slots in the casing wall, and coil springs 30 are arranged between these pins and other pins 31 on the casing wall, the springs acting normally to press the carriage toward the plunger. This pawl or latch 25 is adapted to engage a pin 32 on the locking bar, when the locking bar has been withdrawn from out the opening in the plunger by the slide, and to hold the locking bar in withdrawn position until the pawl i released by a pin 33 on the plunger.

Referring especially to Fig. 8, it will be noted that that end of the latch remote from the pin 32 is in position for engagement by the pin 33 when the plunger is depressed to almost the full extent of its downward movement. The plunger moves in a guide 34 held rigidly in the casing, and it carries a cam 35 near its lower end, which is adapted to engage an extension 36 on the carriage, to move the carriage slightly away from the plunger just as the plunger commences its downward movement.

A follower 37 is arranged at the rear of the packages 3, for moving the packages toward the plungenand the follower has pins at its ends to which are connected springs 38. Flexible members 39 are connected with the other ends of the spring, and these flexible members pass forwardly over pulleys 40 on the walls of the casing and upwardly to wind upon reels 41. These reels are secured to a shaft L2 journaled transversely of the casing in a bracket 43 which is supported by the casing above the magazine. This shaft is provided at its center with a pin wheel 44, the said wheel havingv radial pins arranged at spaced intervals, and the pins are adapted to be engaged by a plate spring 45 held in a groove 46 in the rear wall of the plunger. This spring engages a pin each time the plunger moves downward, and moves the shaft 42 a sufficient distance to move the packages to bring another package beneath the plunger when the plunger shall have lifted.

The springs permit the movement of the reels before the follower moves, that is, before the plunger lifts. On the upward movement of the plunger the spring 45 moves idly past the pins. Aratchet wheel 47 is secured to the shaft adjacent to the pin wheel, and this ratchet is engaged by a spring pressed pawl 48, the pawl preventing reverse movement of the ratchet wheel and of the shaft. The plunger is provided with a handle 49 at its top, and the upperwall of the casing at the magazine has a door 50 for permitting the placing of packages in the magazine. This door may be newest held locked by a lock 51 as shown. A door is also provided in the money receiving chamber, for permitting the money to be withdrawn.

The plunger is moved upward by coil springs 51 which are arranged between the plunger and the guide 34. It will be noticed that the plunger has a cross head 52 at its lower end and that the springs are connected at one endwith the cross head. The springs are arranged at opposite sides of the plunger.

In operation, with the parts in the position of Fig. 2, when a coin is inserted through the guide chute it will fall into the registering notches 19 and 20. The slide is now pulled outwardly, bringing with it the locking bar and the locking bar is locked or held in outward position by the latch 25. As soon as the pull on the slide relaxes the coin will drop through the opening 28 into the coin holding chamber, and the slide will return to its inward position. The locking bar, however, is held by the pawl. The plunger is now moved downward, and a package is pushed, out into the delivery chute 7. As the plunger moves downward, the spring 45 engages a pin, moving the reels and putting the springs 38 under tension. The first downward movement of the plunger moves the carriage outward, which takes with it the locking bar. The continued movement of the plunger to completely drive out a package brings the pin 33 into contactwith the adjacent end of the latch, releasing the same from the locking bar, and when the plunger moves upwardly the locking bar again engages the opening 10. As soon as the plunger has moved upwardly past the packages in the magazine they are pushed forward by the follower.
